Abstract (en)
In a riding concrete finishing trowel, a stabilizer is operatively disposed between the frame and either the gearbox or a structure that is coupled to the gearbox. Such a stabilizer has been found to reduce the effects of rotor assembly vibration on the trowel greater than would be expected and even to improve steering response. In one embodiment, the stabilizer takes the form of a gas spring located between the frame and the pitch control post. Preferably, this gas spring is located relatively close to the top of the pitch control post so as to take advantage of the mechanical advantage offered by the spacing between that location and the gearbox.
